Neutral-current neutrino-nucleus scattering in the quasielastic region

초록

Within the framework of a relativistic single-particle model, we calculate the neutral-current neutrino-nucleus scattering through a knocking-out nucleon process in the quasielastic region. C-12 is used as a target nucleus, and incident energies of 500 MeV and 1.0 GeV are used for the neutrino (antineutrino) scattering. In order to study the final state interaction we use a real potential and a phenomenological optical potential for the knocked-out nucleon. We also investigate the contribution of the strange quark contents in the nucleon. The final state interaction and the strange quark contents exhibit different effects on the cross section and oil the asymmetry.
